Android: Believe it or not, one of the best ways to find great deals on Ebay is with auctions that have misspelled words. So a "Xbox Connect" instead of an "Xbox Kinect" might just go for a lot lesser since fewer people search for that. Eaby makes it easy to find such items on Android.

If you peruse the health and fitness category on Google Play or the iTunes App Store, you'll see thousands of activity trackers that automatically track your location, steps, runs, cycling, and more. It's a bit overwhelming, so here are a few of our favorites in a number of different categories.

OS X: Your Mac likes to cache things in your "free" RAM so if you need them later you can load them quickly. This might be nice sometimes, but if you need to free up a lot of memory for a particular task you might not want it filled with cache files. Memory Clean wipes them out with a couple of clicks.

Android (root): Google's App Ops on Android has had a rough history. It was never a consumer-facing feature and it keeps getting hidden. Now (and for the foreseeable future, most likely), you can access App Ops if you have root via a third-party app.

Android: We're all familiar with incognito mode on most modern browsers. It's the same browsing experience, but with tracking disabled. Dolphin Zero, from the company behind our favorite Android browser, has made an app specifically for this purpose.

Android (4.1+): Previously mentioned Fleksy has been in private beta for a while now, but now it's available at Google Play. Whether you just want to customize the keyboard, or turn it invisible so you can see behind it as you type, Fleksy works well.
